The extent to which you are using borrowed funds to gear your account. Increasing your leverage magnifies both gains and losses. To calculate leverage used, divide total open positions by account equity to get the leverage ratio. e.g. If a trader has $1,000 in his account and opens a $100,000 position, he is leveraging his account by 100 times, i.e. 100:1 leverage. If he opens a $200,000 position with $1,000 in his account, he is leveraging his account by 200 times, i.e. 200:1 leverage.
